Philosophy

Philosophy is the study of the general and fundamental nature of reality, existence, knowledge, values, reason, mind and language. Philosophy has been divided into many sub-fields. It has been divided chronologically (e.g., ancient and modern); by topic (the major topics being epistemology, logic, metaphysics, ethics, and aesthetics); and by style (e.g., analytic philosophy).

As a method, philosophy is often distinguished from other ways of addressing such problems by its questioning, critical, generally systematic approach and its reliance on rational argument.

In casual speech, the term can refer to any of “the most basic beliefs, concepts, and attitudes of an individual or group,” .
